Bearing Life Calculator (L10)

This bearing life calculator works out the rated service life (L₁₀) of a rolling element bearing, based on its basic dynamic load rating, the applied load, and the rotational speed. Optional ISO 281 correction factors let you account for required reliability and lubrication/contamination conditions to give a modified rating life.

Enter the dynamic load rating, applied load and speed, then select bearing type and any correction factors.
